Iyo biva uruganda rukora ibyuma bishora ibyuma abafatanyabikorwa kubintu byingenzi-byingenzi, injeniyeri n'abashinzwe gutanga amasoko ntibakenera gusa uwabitanze-bakeneye kwagura tekinike yitsinda ryabo ryashushanyije. Twabonye imishinga myinshi yatinze gutwarwa nubunini mu nzu ya valve, microcrack mu bice bya pompe ya cobalt-alloy nyuma yo kuvura ubushyuhe, cyangwa kurangiza bidahuye kurangirira ku byuma bidafite umwanda byananiye kwipimisha umunyu mugenzuzi wanyuma. Ibi ntabwo byatsinzwe wenyine. Nibimenyetso byubushobozi bwacitsemo ibice - aho guta, gutunganya, no kugenzura metallurgical bibera muri silos zitandukanye.
Impamvu Vertical Integrated Ikubita "Ibyiza-mu -cyiciro" Outsourcing
Ibyuma bidafite ishoramari gushora bisaba ibirenze gukora no gutesha agaciro. Irasaba kugenzura neza ibyuma bikomera, gutunganya imiterere yintete, no gutandukanya interdendritic-cyane cyane muri 316, 17-4PH, cyangwa amanota ya duplex akoreshwa mumavuta na gaze cyangwa sisitemu ya hydraulic. Abatanga isoko benshi batanga ubushyuhe bwo kuvura cyangwa kurangiza CNC. Ibyo bitera icyuho cya handoff: kwihanganira mm 0,02 kuri pisitori ya pompe ya pompe ya pompe irashobora gucika mugihe cyo kugabanya imihangayiko niba umwirondoro witanura udahujwe na microstructure ya casting.
Twakoranye nabakiriya bahinduye mubacuruzi batatu batandukanye (caster → ubushyuhe bwo kuvura → machinist) bahinduka umufatanyabikorwa umwe uhujwe-kandi tugabanya igihe cyose cyo kuyobora ku kigero cya 38%, tugabanya ibice byingingo ya mbere kuri 62%, kandi dukuraho imirimo kubera ibisobanuro bya GD&T bidahuye. Itandukaniro ntabwo ryari ryoroshye gusa. Byakurikiranwe: umubare munini uva kuri bilet mbisi kugeza igice cyarangiye, umukoresha umwe wa CMM yemeza byombi nka geometrie hamwe nibikoresho bya nyuma byakozwe, metallurgiste umwe yemeza ibisubizo byombi hamwe na passivation nyuma yo gutunganywa.
Uru rwego rwo kwishyira hamwe ntirusanzwe-sibyo kuko bidashoboka mubuhanga, ariko kubera ko bisaba kuvuga neza. Ukeneye injeniyeri usoma AMS 5387 urupapuro rwihariye nka roman na mashini bahindura igipimo cyibiryo ukurikije intera ya dendrite igaragara munsi ya SEM.
Igiciro nyacyo cya "Bisanzwe" Ibyuma bidafite ibyuma
Abaguzi bamwe batekereza ko ibyuma 304 byose bidafite ibyuma bishora imari. Ntabwo aribyo. Twigeze kugenzura icyiciro cyimibiri "isanzwe" 304 ya valve yahawe OEM yu Burayi. Isesengura rya laboratoire ryagaragaje ko chromium igabanuka ku mbibi z’ingano - biterwa no kumara igihe kinini mu ishoramari mbere yo kurasa. Ibice byatsinze ibizamini ariko byananiye kwangirika kwangirika mumasaha 48 yo kwishyiriraho. Intandaro? Amaduka ya casting yatunganijwe neza, ntabwo ari ubunyangamugayo.
Imikorere nyayo ishingiye ku bintu bine bidashobora kuganirwaho: kwemeza ibikoresho fatizo bikurikiranwa (umubare wubushyuhe winjiye mugihe cyo gufata), kugenzura ikirere gishonga (argon cyangwa vacuum ya reaction ya alloys), ibishushanyo mbonera byahinduwe kugirango bihindurwe no kwaguka kwinshi, hamwe nigisubizo cya nyuma cyakorewe ibizamini bya ruswa hagati ya ASTM A262 Imyitozo E. Gusiba intambwe zose zatewe no kunanirwa neza, gushira mu gaciro.
Niyo mpamvu kuyobora uruganda rukora ibyuma bishora ibyuma abafatanyabikorwa bashora imari mu nzu ya spekitroscopi, laboratoire ya metallografiya, hamwe namakuru yinjira mu itanura ryahujwe na sisitemu ya ERP. Ntabwo ari ikinamico yemewe - ahubwo ni uguhuza buri cyiciro cyo kuvura ubushyuhe hamwe namakarita nyayo ya microhardness mubice bikomeye.
Aho Cobalt Alloys Yerekana Ibyuho Byubushobozi
Niba ibyuma bidafite ingese byerekana disipuline, cobalt-nikel superalloys yerekana ubujyakuzimu bwa tekinike. AMS 5387 cobalt alloy 6, T800, na Stellite ntabwo irwanya kwambara-barabisaba. Gukomera kwabo (45-55 HRC as-cast) bituma basa nkibidashoboka gukora imashini badafite ibikoresho byabugenewe kandi bishyizeho. Nyamara amaduka menshi aracyavuga ibice akoresheje amasomero rusange ya CNC.
Twabonye cobalt nozzles yanze "burr ikabije" nyuma ya EDM irangije-gusa twasanze burr mubyukuri yari recast layer kuva indishyi zidakwiye za electrode. Abandi bananiwe kwipimisha igitutu kubera ko igishoro cyogukoresha ubushyuhe bwumuriro nticyahinduwe kugirango ubushyuhe buke bwa cobalt bugabanuke, bigatuma habaho kugabanuka kwimitsi hafi yimiterere yurukuta.
Abahanzi bakomeye bafata cobalt ntabwo ari "ikindi cyuma gusa," ariko nka sisitemu: gushushanya ibicuruzwa byabigenewe, imyirondoro y’itanura rya zone nyinshi, uburyo bwo kuvanga (gushora imari + gusya neza aho kuba CNC yuzuye), hamwe no kwerekana amashusho yumuriro mugihe cyo kwangiza. Ibi ntabwo ari theoretical. Nicyo gitandukanya prototypes ikora nibice byiteguye gukora bikomeza kubaho 10,000+ cycle mumateraniro ya pompe yo mumazi.
Ibyo Kugenzura Mbere yo Kurangiza Umufatanyabikorwa wawe
Ntukishingikirize ku gatabo cyangwa ibyemezo bya ISO wenyine. Baza ibimenyetso byerekana imyitwarire ikora:
- Gukurikirana ibikoresho: Bashobora gutanga raporo yikizamini gihuza numero yawe ya PO - kandi bakerekana uburyo ubushyuhe butemba binyuze muri casting, kuvura ubushyuhe, no gutunganya ibiti?
- Kwemeza ibipimo: Bakoresha CMM hamwe nubushyuhe bwishyurwa kubice bitagira umwanda na cobalt? (Ibipimo bidakosowe bigenda bigera kuri 0,015 mm / ° C.)
- Gutunganya inyandiko?
- Igisubizo cyatsinzwe: Iyo igice cyananiwe kugenzura bwa nyuma, bakora isesengura-nyirabayazana-cyangwa gukora gusa no kohereza?
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yujuje ibi bipimo. Ikigo cyacyo cya Qingdao gikomatanya gushora imari, gutunganya imirongo myinshi ya CNC, hamwe no gutunganya ubushyuhe mu nzu munsi yinzu imwe - hamwe n’ubushakashatsi bwuzuye kuva kuri T800 cobalt fagitire kugeza kuri AMS 5387. Ba injeniyeri basanzwe bafatanya gusubiramo GD&T guhamagarwa mugihe cyo guhagarika igishushanyo, kwerekana ibishobora kuvamo ibicuruzwa mbere yo gutangira. Ntabwo ari serivisi. Nibisangiwe gutunga ibikorwa byizewe.
Ku makipe agaragaza ishoramari ry’icyuma, ikibazo ntabwo "Ninde utanga amagambo yo hasi?" Ni "Ninde umaze gukemura ikibazo ntarahura nacyo?" Igisubizo kiri mubikorwa byanditse - ntabwo ari amagambo yo kwamamaza. Shakisha abafatanyabikorwa aho metallurgie itari ishami, ahubwo sisitemu y'imikorere.
